I had seen images from drag racing which showed how the tires get distorted as the immense amounts of torque are transferred through them.  A tire is at its most effective when it isn’t sliding but is in static contact with the ground.  You might recognize this from your own experience.  If you push something across a surface, the resistance reduces once the item starts moving.  The same thing happens with tires.  To get the best out of them spinning is not good.  With the tire gripping the surface but the axle rotating, the sidewall is the area that has to compensate which it does by distorting and then unloading as it drives the vehicle forwards.  I wanted to try and catch this so took a bunch of shots focused on trying to catch this moment.
